Having milk but the milk eye does not work may be related to simple milk duct incompatibility, mastitis, tumors and other factors. It can be solved by breast pump, breast rubbing and surgery. 1. Simple milk ducts: usually occurs in the early stage of breastfeeding, when the hormones stimulate the milk ducts so that they have not yet opened. At this time, you can use a breast pump to suck out the secretions in the milk ducts, thus unclogging the milk ducts and promoting the discharge of milk. 2. Mastitis: If mastitis causes a blockage of the milk ducts, so that the milk eye is not accessible, you can gently rub the breast and with hot compresses, can be repeated several times, dredge the milk ducts, promote the discharge of milk. If necessary, you can follow the doctor’s instructions to use cefradine, cefdinir and other antibiotics for treatment. 3. Tumor: If the breast ducts are not accessible and there are lumps and pain in the chest at the same time, there may be tumors, which can be treated with surgical excision after milk return if necessary. It is recommended that after the cause of the disease is clearly defined, appropriate methods of treatment should be taken to unblock the milk eye, so that the milk can be discharged.
